Bruce Lee makes a brief appearance in this vintage martial arts action drama, which stars his longtime friend and mentor Unicorn Chan. When a rover named Lung is befriended by a young man named Tiger, he accepts an invitation to join Tiger and his mother in their home, and stays on as their handyman. Lung enjoys the stability of his new life, but when Tiger impulsively offends Wong, the violent and short-tempered son of a notorious gangster, Lung must step forward to defend him. Lung and Tiger soon join forces with a young woman who is being pursued by Wong after he killed her partners in an acrobatic troupe, and Lung shares his knowledge of the martial arts with his new friends in order to even the score between themselves and Wong's minions. Bruce Lee helped to choreograph and direct the action sequences in Fist of Unicorn as a favor to Unicorn Chan; behind-the-scenes footage of Lee rehearsing the actors and stuntmen was edited into the film to create Lee's cameo role.
